Bro, take a deep breath.
-Buy a 60 day tourist visa.
-Buy a refundable ticket for 29 days after you arrive.
-Insurance is only sold in 30 day increments. Buy a 30 day policy.
When you arrive, you'll get stamped in for 60 days. Change your flight ticket to whenever you want after you enter the country. That's it.
